[all variants] Help understanding MIDI, JACK, and ALSA

view story

http://ubuntuforums.org – Hey all, I need some help understanding how JACK, ALSA, and MIDI interact. Specifically, I want to understand why I'm having so much trouble routing MIDI traffic between different devices and programs. Even more specifically: I have an ancient MIDI keyboard. Well, it's sort of a MIDI keyboard. It was originally designed to be used with some wretched old keyboard training software for MS-Something 95, and instead of a real MIDI port, it plugs into a SoundBlaster Game port, gets its power from that, and sends MIDI signals to the PC that way, without any need for the r@re proper MIDI (Hardware)
